An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-40780 in the wild and no public exploit code.\n\nAffected product: ISC BIND 9. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-40780/ (Markdown: https://insights.sbomify.com/CVE-2025-40780/index.md)","id":"CVE-2025-40780","markdown":"https://insights.sbomify.com/CVE-2025-40780/index.md","name":"CVE-2025-40780","record":{"aliases":["ALPINE-CVE-2025-40780","AZL-68730","AZL-68739","BELL-CVE-2025-40780","DEBIAN-CVE-2025-40780","GHSA-j3w4-m6qj-vmm5","MINI-p5rg-j6p2-6jj4","UBUNTU-CVE-2025-40780"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"BIND DNS server","requires_auth":"none","summary":"Attackers can predict DNS query parameters due to weak PRNG, enabling cache poisoning attacks against BIND servers.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-341","name":"Predictable from Observable State"}],"description":"In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use.\nThis issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Cache poisoning due to weak PRNG","id":"CVE-2025-40780","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in SIMATIC PCS neo V4.1","id":"CVE-2025-40795"},"packages":[],"prev":{"headline":"Kea crash upon interaction between specific client options and subnet selection","id":"CVE-2025-40779"},"products":["BIND 9"],"published":"2025-10-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-04","vendors":["ISC"]},"summary":"Attackers can predict DNS query parameters due to weak PRNG, enabling cache poisoning attacks against BIND servers.","url":"https://insights.sbomify.com/CVE-2025-40780/"}
